With reference to Fig. 4 A and Fig. 4 B, heater block 300 is described.Heater block 300 is the heat generating components producing heat.Heater block 300 uses the substrate 311 of aluminium oxide material to be formed.At the side interarea of substrate 311---be namely formed with the resistance pattern 313 that heating Pt thin film is made on the surface.In addition, the surface of substrate 311 is formed with a pair rectangular electrode 315 be connected with the two ends of resistance pattern 313 respectively.Except being formed with the part of electrode 315, the surface of substrate 311 comprising resistance pattern 313 is formed with insulation polyimide film 317.The whole back side of substrate 311 is formed with joint metal level 319.Electrode 315 and joint metal level 319 are the multilayer films be made up of such as Ti, Cu, Ni and Au.Electrode 315 and joint metal level 319 have stable intensity when carrying out wire-bonded or welding.Joint metal level 319 arranges to be welded on the 1st high-frequency electrode 266 with stable conjugation grade by heater block 300.
Then, with reference to Fig. 5 A and Fig. 5 B, repeater chip 321 is described.Repeater chip 321 uses the substrate 323 of aluminium oxide material to be formed in the same manner as heater block 300.The surface of substrate 323 defines the electrode 325 of rectangle.In addition, the whole back side of substrate 323 is formed with joint metal level 327.Connect chip 331 and also there is the structure identical with repeater chip 321.As shown in Figure 6, connect chip 331 comprise substrate 333 that aluminium oxide makes, be formed in substrate 333 surface on electrode 339 and the joint metal level that is formed on the whole back side of substrate 333.
Heater block 300, repeater chip 321 are disposed in the back side of the 1st high-frequency electrode 266 with being connected chip 331, the reverse side in the face namely contacted with bio-tissue.Here, heater block 300, repeater chip 321 and be connected the back side of chip 331 respectively by the surface and the 1st high-frequency electrode 266 that are weldingly fixed on joint metal level.1st high-frequency electrode 266 and resistance pattern 313, electrode 325 and electrode 339 utilize substrate 311,323,333 to form insulation by this way.
On the 1st high-frequency electrode 266,6 heater blocks 300 are joined together according to mode shown in Fig. 7.That is, heater block 300 is configured with 2 row in the position across sickle guide channel 262a symmetry, and the long axis direction along the 1st high-frequency electrode 266 often arranges each configuration 3.In addition, repeater chip 321 is configured with at the fore-end of the 1st high-frequency electrode 266.In addition, the base end part of the 1st high-frequency electrode 266 divide across the position of sickle guide channel 262a symmetry be respectively configured with 1 connect chip 331.
A base portion 337 connecting chip 331 is welded heater block live wire 268a wherein, and the base portion 337 connecting chip 331 at another is then welded heater block live wire 268b.This heater block is paired with live wire 268a and heater block live wire 268b, is connected to energy source 214 via cable 228.The leading section 335 connecting chip 331 utilizes the lead-in wire 353 formed by wire-bonded to be connected with the electrode 315 of the heater block 300 nearest apart from leading section 335.In addition, the lead-in wire 351 formed by wire-bonded is also utilized to be connected each other at the electrode 315 of the adjacent heater block 300 of long axis direction.
In the leading section of the 1st high-frequency electrode 266, each electrode 315 of heater block 300 utilizes the lead-in wire 351 formed by wire-bonded to couple together by the electrode 325 of repeater chip 321 each other.Namely, the electrode 315 being positioned at heater block 300 is foremost coupled together by lead-in wire 351 with the electrode 325 of repeater chip 321, and another electrode 315 being positioned at heater block 300 foremost is also coupled together by lead-in wire 351 with the electrode 325 of repeater chip 321.Why connected by repeater chip 321, be because, and compared with the interval being arranged in the heater block 300 of the long axis direction of the 1st high-frequency electrode 266, the interval of 2 heater blocks 300 on the direction that the leading section of the 1st high-frequency electrode 266 is configured in and the long axis direction of the 1st high-frequency electrode 266 is orthogonal is larger, is difficult to be connected by wire-bonded.
In this manner, 6 heater blocks 300 of the arrangement in U-shaped, repeater chip 321 and be connected chip 331 and formed by lead-in wire 351 and be connected in series.Therefore, the electric current exported from energy source 214 will connect chip 331 via heater block live wire 268a arrival, and flows to the resistance pattern 313 of heater block 300 via lead-in wire 351.Consequently, resistance pattern 313 generates heat.After resistance pattern 313 generates heat, its heat will be passed to the 1st high-frequency electrode 266.Consequently, the bio-tissue contacted with the 1st high-frequency electrode 266 is burnt.In addition, the 1st holding member main body 272 is preferably covered with the periphery of heater block 300 and has thermal insulation.Utilize this structure can realize low-loss conduction of heat.

In addition, in the present embodiment, the size of heater block 300 is such as long about 3mm, wide about 1.2mm.In addition, the size of the 1st high-frequency electrode 266 is the length of such as long axis direction is about 35mm, wide about 7mm, is formed with along its central shaft the sickle guide channel 262a etc. that width is about 1mm.
As shown in Figure 8, control part 290, high frequency (HF) energy output circuit 292, heating factor_driven circuit 294, input part 295, display part 296 and speaker 298 is equipped in the inside of energy source 214.Control part 290 is connected to high-frequency energy output circuit 292, heating factor_driven circuit 294, input part 295, display part 296 and speaker 298.Control part 290 controls each several part of energy source 214.High-frequency energy output circuit 292 is connected to energy treatment tool 212, under the control of connecting portion 290, drives the 1st high-frequency electrode 266 of energy treatment tool 212 and the 2nd high-frequency electrode 270.Heating factor_driven circuit 294 is connected to energy treatment tool 212, under the control of control part 290, drives the heater block 300 of energy treatment tool 212.Control part 290 is connected to foot switch (SW) 216, and when inputting ON from foot switch 216, energy treatment tool 212 performs disposal, and during input OFF, energy treatment tool 212 stops disposing.The various settings in input part 295 input control portion 290.Display part 296 demonstrates the various settings of control part 290.Speaker 298 exports audio warning etc.
In addition, high-frequency energy output circuit 292 exports high-frequency energy, and can detect resistance Z.That is, high-frequency energy output circuit 292 possesses the sensor function measured the resistance Z of the bio-tissue between the 1st high-frequency electrode 266 of energy treatment tool 212 and the 2nd high-frequency electrode 270.In addition, heating factor_driven circuit 294 supplies energy to heater block 300 thus heater block 300 is generated heat, and possesses the sensor function measured the heating temp T of heater block 300.
The following describes the action of the treatment disposal plant 210 of present embodiment.The input part 295 in operative doctor operating energy source 214 in advance, sets the output condition for the treatment of disposal plant 210.Specifically, the design temperature Tset [DEG C], t heat time heating time [sec] etc. of the setting power Pset [W] of high-frequency energy output, heat energy output is set.Both can adopt the structure individually setting each value, also can adopt the structure of the combination according to different surgical selection setting value.
The maintaining part 226 of energy treatment tool 212 and axle 224 are inserted into intraperitoneal when maintaining part 226 is in closure state as shown in Figure 2 A through such as stomach wall.Once maintaining part 226 is close to the bio-tissue as disposal object, operative doctor is with regard to the maintaining part opening and closing knob 232 of operating grip 222, open or close the 1st holding member 262 and the 2nd holding member 264, to grasp the bio-tissue as disposing object.That is, first, overlap 244 to move to base end side relative to cylindrical shell 242.Consequently, the 2nd holding member 264 utilizes the active force of elastic component 280a and opens relative to the 1st holding member 262.
Under the state that maintaining part 226 is opened, bio-tissue is placed between the 1st holding member 262 and the 2nd holding member 264.In this state, the front that 244 are moved to cylindrical shell 242 is overlapped.Consequently, overlapping 244 makes the 2nd holding member 264 overcome the active force of elastic component 280a and close relative to the 1st holding member 262.Like this, maintaining part 226 utilizes the 1st holding member 262 and the 2nd holding member 264 to grasp as disposing the bio-tissue of object.At this moment, come in contact with the 1st high-frequency electrode 266 be arranged on the 1st holding member 262 and the 2nd high-frequency electrode 270 both sides be arranged on the 2nd holding member 264 as the bio-tissue disposing object.
Operative doctor, after the bio-tissue utilizing maintaining part 226 to grasp as disposal object, namely operates foot switch 216.When foot switch 216 switches to ON, supply the RF power of the setting power Pset [W] preset to the 1st high-frequency electrode 266 and the 2nd high-frequency electrode 270 via cable 228 from energy source 214.The electric power supplied is such as 20 left and right, [W] ~ 80 [W].Like this, high frequency electric will flow through the bio-tissue as disposal object be grasped between the 1st holding member 262 and the 2nd holding member 264.Consequently, bio-tissue generates heat, and organizes and is burnt (tissue rotten).
When organize burnt time, bio-tissue can discharge the fluid gases such as liquid and/or steam such as () such as blood.Here, the supporting surface 272b of the 1st the holding member 262 and supporting surface 276b of the 2nd holding member 264 than the 1st high-frequency electrode 266 and the 2nd high-frequency electrode 270 more outstanding.Therefore, supporting surface 272b and supporting surface 276b plays the effect of barrier portion (burrock), makes fluid reside in the inner side of the 1st holding member 262 and the 2nd holding member 264.
If attracted from the fluid outlet 244a of the cover 244 and fluid outlet 242a of cylindrical shell 242, the fluid so residing in the inner side of the 1st holding member 262 and the 2nd holding member 264 will flow through sickle guide channel 262a, 264a inside, cylindrical shell 242 is inner, discharges from fluid outlet 242a and fluid outlet 244a.During bio-tissue release fluids, as mentioned above, fluid is continued to discharge.Consequently, the fluid discharged under the state that can either prevent bio-tissue from rising in temperature causes thermal diffusion (thermal spread), can prevent from again impacting non-disposal object part.
Then, energy source 214 is powered to heater block 300, the Tset [DEG C] temperature of heater block 300 being reached preset.Here set temperature Tset is such as 100 [DEG C] ~ 300 [DEG C].Electric current now from energy source 214 by cable 228, heater block live wire 268a, connects the lead-in wire 353 that chip 331 and wire-bonded formed, inflow is configured in the resistance pattern 313 of the heater block 300 on the 1st high-frequency electrode 266.This electric current makes resistance pattern 313 generate heat.The heat that resistance pattern 313 produces, via substrate 311 and joint metal level 319, is transmitted to the 1st high-frequency electrode 266.Consequently, the temperature of the 1st high-frequency electrode 266 rises.Similarly, electric current, via cable 228, heater block live wire 269a, flows into the resistance pattern 313 of the heater block 300 be configured on the 2nd high-frequency electrode 270.At this moment, this resistance pattern 313 generates heat.This conduction of heat rises to the temperature of the 2nd high-frequency electrode the 270,2nd high-frequency electrode 270.Consequently, the bio-tissue contacted with the 1st high-frequency electrode 266 or the 2nd high-frequency electrode 270 solidifies.
Namely the output of high-frequency energy and heat energy is stopped after bio-tissue solidifies.Finally, operative doctor operation sickle drives knob 234.Consequently, sickle 254 moves in sickle guide channel 262a, 264a, is blocked by bio-tissue.As above, namely the disposal of bio-tissue has accused.
But, once define resistance pattern 313 on the composition surface of the 1st high-frequency electrode 266 and heater block 300, be just difficult to lead-out wiring.Therefore, in the present embodiment, resistance pattern 313 be formed in be different from heater block 300 with on the interarea on the composition surface (being formed with the face of joint metal level 319) of the 1st high-frequency electrode 266.Like this, if consider wiring process, then in heater block 300 normally be different from the face on the composition surface of the 1st high-frequency electrode 266 on form resistance pattern 313.
But, contacting with the bio-tissue as heating target thus correctly can there is substrate 311 between the 1st high-frequency electrode 266 of control temperature and resistance pattern 313, therefore, between the 1st high-frequency electrode 266 and resistance pattern 313, create temperature difference.This temperature difference changes along with the state of the 1st high-frequency electrode 266, resistance pattern 313 and bio-tissue.Especially, be with little heater block 300 to heat the 1st large high-frequency electrode 266 in the present embodiment, therefore, when increasing from the heat flux density of resistance pattern 313 to the 1 high-frequency electrode 266, this temperature difference becomes large.In the present embodiment, consider this temperature difference, control the input to resistance pattern 313, make the temperature of the 1st high-frequency electrode 266 be fixed on set temperature Tset.
The temperature of the 1st high-frequency electrode 266 that makes that the following describes in present embodiment is fixed on the control method of design temperature Tset.In the present embodiment, based on the resistance value of the pattern 313 of heater block 300, obtain the temperature of resistance pattern 313, and then, consider the temperature difference of resistance pattern 313 and the 1st high-frequency electrode 266, the temperature of the 1st high-frequency electrode 266 is controlled regularly at design temperature Tset.

In step s 103, control part 290 calculates the electric current I of flowing in resistance pattern 313 and monitor resistance 420 based on obtained potential difference V_m.Here, because the resistance value R_m of monitor resistance 420 is known, so electric current I can be calculated by following formula (1).
Ｉ＝V_m/R_m……（1）
In step S104, control part 290 uses the electric current I calculated, and calculates the resistance value R_heat of heater resistance 410.Here, resistance value R_heat is calculated by following formula (2).
R_heat＝（V_h/Ｉ）－R_m……（2）
In step S105, control part 290 uses the resistance value R_heat calculated to calculate the temperature Trp of resistance pattern 313.The relation of the temperature Trp of known resistance pattern 313 and the resistance value R_heat of heater resistance 410 can be expressed as following formula (3).
Trp＝C1×R_heat＋C2……（3）
Here, C1 and C2 is constant.Constant C1 and constant C2 is in advance by such as testing or numerical analysis acquisition.The temperature Trp of resistance pattern 313 can calculate based on this relational expression (3).
In step s 106, control part 290 calculates the connection power P connected to resistance pattern 313.Here, connect power P to be calculated by following formula (4).

In step s 107, control part 290 calculates the estimation temperature Thfe of the 1st high-frequency electrode 266.Temperature difference Δ T and the heat flux density q roughly direct proportionality from resistance pattern 313 to the 1 high-frequency electrode 266 of the temperature Trp of resistance pattern 313 and the temperature of the 1st high-frequency electrode 266.Here, from heat flux density q and the connection power P roughly direct proportionality connected to resistance pattern 313 of resistance pattern 313 to the 1 high-frequency electrode 266.Therefore, the temperature difference Δ T of the temperature Trp of resistance pattern 313 and the temperature of the 1st high-frequency electrode 266 can use constant C3 to be expressed as following formula (5).
ΔT＝C3×P……（5）
As from the foregoing, the estimation temperature Thfe of the 1st high-frequency electrode 266 can use the temperature Trp of resistance pattern 313 to be calculated by following formula (6).
Thfe＝Trp－C3×P……（6）
Constant C3 also can based on the size of heater block 300, material etc. by calculating.In general, the thickness of constant C3 and substrate 311 is in direct ratio, is inversely proportional to the area of substrate 311 and pyroconductivity.In addition, also can test, the temperature of the resistance pattern 313 under various connection power condition and the temperature of the 1st high-frequency electrode 266 are carried out to actual measurement and tried to achieve constant C3.In addition, also the temperature of the temperature of the 1st high-frequency electrode 266 and joint metal level 319 can be regarded as equal temperature.
In step S108, control part 290 calculates the power P _ next that next will connect based on the estimation temperature Thfe of design temperature Tset and the 1st high-frequency electrode 266.What adopt in the present embodiment is simple control, that is, current connection power P basis changes according to the directly proportional ratio of temperature difference of the estimation temperature Thfe with design temperature Tset and the 1st high-frequency electrode 266.Power P _ the next that next will connect can be expressed as following formula (7).
P_next＝（Tset－Thfe）×C4/P＋P……（7）
Here, C4 is constant, represents gain.
In step S109, control part 290 calculates the voltage V_h for turning on the variable voltage source needed for power P _ next of setting in step S108.Here, variable voltage source V_h is calculated by following formula (8).
V_h＝（P_next×R_heat）
0.5……（8）
In step s 110, control part 290 is according to variable voltage source output voltage V_h set in step S109.
In step S111, control part 290 judges whether the elapsed time counted from control start time has exceeded T heat time heating time preset.If the result judged is through the time do not exceed heat time heating time, process then returns step S102, repeats process similar to the above.If judge to find that the elapsed time has exceeded heat time heating time in step S111, process then enters step S112.

[the 2nd embodiment]
Below, the 2nd embodiment of the present invention is described.Here, be only described for the difference with the 1st embodiment in the declarative procedure of the 2nd embodiment, identical symbol is marked to identical part, and the description thereof will be omitted.In the 1st embodiment, the temperature of heater block 300 is tried to achieve based on the resistance value of resistance pattern 313.In contrast to this, in the present embodiment, temperature measurement electricity consumption resistance pattern is configured with to obtain the temperature of heater block.
Figure 11 represents the structure example of the heater block 500 used in present embodiment.As shown in the drawing, heater block 500 forms resistance pattern 513 in the same manner as the heater block 300 in the 1st embodiment on the surface of substrate 511, and forms electrode 515 at its two ends.On the surface of substrate 511, form thermometric resistance pattern 563 further in the present embodiment, and form electrode 565 at its two ends.
Figure 12 represents the structure of the 1st high-frequency electrode 266 of present embodiment, heater block 500, repeater chip 521 and the wiring being connected chip 531 and they coupled together etc.As shown in the drawing, the 1st high-frequency electrode 266 is configured with in a same manner as in the first embodiment 6 heater blocks, 500,1 repeater chip 521 and is connected chip 531 with 2.In the present embodiment, as shown in figure 11, heater block 500 is formed with resistance pattern 513 and thermometric resistance pattern 563, correspondingly, repeater chip 521 has the electrode of more than 2 respectively with being connected chip 531.
As shown in figure 12, be formed on 1 electrode 539 on a connection chip 531 and be connected to heater block live wire 268a in a same manner as in the first embodiment.Similarly, be formed on 1 electrode 539 on another connection chip 531 and be connected to the heater block live wire 268b paired with heater block live wire 268a.In addition, be formed on another electrode 569 on a connection chip 531 and be connected to thermometric live wire 570a.Similarly, be formed on another electrode 569 on another connection chip 531 and be connected to thermometric live wire 570b.
Connect the electrode 539 that chip 531 is connected with heater block live wire 268a, 268b and the electrode 515 be connected with the resistance pattern 513 of adjacent heater parts 500 utilize the lead-in wire 553 formed by wire-bonded to couple together.The electrode 515 connected at the resistance pattern 513 of the adjacent heater block 500 of long axis direction also utilizes the lead-in wire 551 formed by wire-bonded to couple together each other.In the leading section of the 1st high-frequency electrode 266, across sickle guide channel 262a, the electrode 515 of relative heater block 500 couples together via the electrode 525 be formed on repeater chip 521 each other.
Connect the electrode 569 that chip 531 is connected with thermometric live wire 570a, 570b and the electrode 565 be connected with the thermometric resistance pattern 563 of adjacent heater parts 500 utilize the lead-in wire 571 formed by wire-bonded to couple together.Also the lead-in wire 572 formed by wire-bonded is utilized to couple together at the thermometric of the adjacent heater block 500 of long axis direction each other with the electrode 565 that resistance pattern 563 connects.In addition, in the leading section of the 1st high-frequency electrode 266, across sickle guide channel 262a, the electrode 565 of relative heater block 500 couples together via another electrode 575 be formed on repeater chip 521 each other.
Connect in this manner, just can apply voltage via heater block live wire 268a, 268b to resistance pattern 513.Similarly, voltage can be applied via thermometric live wire 570a, 570b to thermometric resistance pattern 563.That is, separately voltage can be applied to resistance pattern 513 and thermometric resistance pattern 563.
Figure 13 represents the resistance pattern 513 of heater block 500 and the circuit diagram of thermometric resistance pattern 563 and heating factor_driven circuit 294.In the present embodiment, monitor resistance 420 and thermometric resistance pattern 563 are connected in series.Resistance pattern 513 applies variable voltage V_h by variable voltage source 430 in a same manner as in the first embodiment.On the other hand, thermometric resistance pattern 563 applies by fixed voltage source 450 constant voltage that magnitude of voltage is V_s.Here, the electric power to thermometric resistance pattern 563 connection is very little compared with the electric power connected to resistance pattern 513.Such as, when starting to heat, in order to the 1st high-frequency electrode 266 being heated to more than 200 DEG C at about 5 seconds, connect the electric power of hundreds of W to resistance pattern 513, and the electric power consumed in thermometric resistance pattern 563 is at several about W.In addition, the potential difference at voltage measuring device 440 pairs of monitor resistance 420 two ends measures.Here, in the present embodiment, the total resistance of the thermometric resistance pattern 563 be connected in series 6 is expressed as R_heat.
By using structure as above, in the control procedure with reference to the 1st embodiment illustrated by Figure 10, if voltage V_h is replaced with voltage V_s, and use the resistance R_heat of thermometric resistance pattern 563, also can implement the control identical with the 1st embodiment so in the present embodiment.
In addition, also can adopt using constant-current source instead of fixed voltage source 450 as power supply and use the structure that the potential difference at the total resistance R_heat two ends of voltage measuring device 440 pairs of thermometric resistance patterns 563 measures.In this case, adopt in step S102 to step S104 based on fixing current value and add up to the potential difference meter at resistance R_heat two ends to calculate the mode adding up to resistance R_heat.In this case, treatment disposal plant 210 also can realize the function same with the 1st embodiment illustrated by reference Figure 10.
Obtain the temperature of resistance pattern 513 by the resistance value of measurement resistance pattern 513 in the 1st embodiment.In contrast to this, in the present embodiment, the temperature of thermometric resistance pattern 563 is obtained by the resistance value of measurement thermometric resistance pattern 563.Resistance pattern 513 and thermometric resistance pattern 563 configure near same of substrate 511, and therefore, the temperature of thermometric resistance pattern 563 can be regarded as the temperature of resistance pattern 513.
At the initial stage starting to heat, in order to make the temperature of the 1st high-frequency electrode 266 reach design temperature Tset, high-power electric must be connected to resistance pattern 513.On the other hand, after the temperature of the 1st high-frequency electrode 266 reaches design temperature Tset, in order to keep temperature to resistance pattern 513.Electric power then so not large.Like this, the amplitude of variation to the amount of power of resistance pattern 513 connection is very large.That is, the amplitude of variation of the magnitude of voltage V_h applied is very large.Therefore, as the 1st embodiment on resistance pattern 513 Tandem Connection Monitor device resistance 420 in the structure utilizing the potential difference V_m at voltage measuring device 440 pairs of monitor resistance 420 two ends to measure, the potential difference V_m at monitor resistance 420 two ends will change on a large scale.In this case, the change of the potential difference V_m that the change of the resistance value R_heat caused by the variations in temperature of resistance pattern 513 causes must be detected in the significantly change procedure applying magnitude of voltage V_h.Therefore, require that voltage measuring device 440 has high measurement precision.In addition, refer in the computational process of the resistance value R_heat in step S104 and apply magnitude of voltage V_h, therefore, also require that the output of variable voltage source 430 has High Linear.
On the other hand, in the present embodiment, monitor resistance 420 and thermometric resistance pattern 563 are connected in series, and then apply constant voltage V_s by fixed voltage source 450 to them.Therefore, with regard to the potential difference V_m at monitor resistance 420 two ends, as long as the change of the potential difference V_m that the change of the resistance value R_heat caused by the variations in temperature of thermometric resistance pattern 563 causes can be detected, so the measurement ratio using voltage measuring device 440 to implement is easier to.In addition, have references to the magnitude of voltage V_s that fixed voltage source 450 applies in the computational process of the resistance value R_heat in step S104, thus the linear problem of power supply is also little.In addition, the precision of variable voltage source 430 does not affect temperature measurement, and thus the design of variable voltage source 430 is not by the restriction of temperature measurement.In addition, although require that frequency is enough high after replacing with variable voltage source 430, also therefore can be controlled by pulse width modulation.And then, in the present embodiment, in a heater block 500, define resistance pattern 513 and thermometric resistance pattern 563.Therefore, the structure of the 1st high-frequency electrode 266 of present embodiment is simple, and manufacturing cost is lower.
As mentioned above, according to the present embodiment, comparatively cheap variable voltage source 430 and voltage measuring device 440 can be used and realize high-precision temperature and control.Especially, present embodiment is applicable to make the temperature of the 1st high-frequency electrode 266 or the 2nd high-frequency electrode 270 reach design temperature at short notice and strengthens the design of maximum connection amount of power.
